I've always thought the event horizon for a black hole has to be spherical.

But my physics intuition tells me that as two of them merge, the resulting BH should have a "peanut" shape, at least initially.

And maybe it can keep having an irregular shape, depending on the mass distribution inside it?

Is there a "mass distribution" inside? AFAIK a black hole is a singularity which means it's mass is in one (infinitely small) point.
